The invention also relates to a system for regulating the temperature in a dwelling.

The invention relates to the general technical field of heating and more particularly that of home heating systems equipped with a thermostat.

State of the art

Home heating systems with an intelligent thermostat connected to heaters are known. The thermostat generally controls the heating of the heaters so that the ambient temperature inside the house is approximately equal to a predetermined set temperature. Depending on their level of evolution, the thermostats may comprise means for modifying the desired setpoint temperature according to certain time ranges. The management of time zones and setpoint temperatures is centralized and is performed at a box comprising a user interface. This kind of system then requires the intervention of the user to make the optimal settings. However, the user interfaces are generally Such adjustments and adjustments are often difficult for the unskilled user, who may in some cases use specialized companies to perform them.

Smart thermostats can also be connected to a climate weather forecasting means so as to adapt the heating of the heaters so as to quickly obtain the set temperature despite a low outside temperature. This kind of system favors the user's comfort at the expense of energy balance. Indeed, the higher the temperature gradient between the outside and the inside, the greater the energy losses are important.

Description of the figures.

Other advantages and characteristics of the invention will appear better on reading the description of a preferred embodiment which follows, with reference to the appended drawings, carried out as indicative and non-limiting examples and in which: 1 schematically represents an overview of the economic regulation system of the temperature of a dwelling according to the invention, Figure 2 schematically shows the interactions of the various components of the system object of the invention shown in Figure 1 ,

Embodiments of the invention

The solution proposed by the invention is a system for regulating the temperature in a dwelling (0). The dwelling can include one or more rooms.

Referring to Figure 1, the system includes heating devices (1). These are in the form of water radiator, oil bath, convectors, or any other heating device suitable for the skilled person. The heating devices (1) are generally arranged inside the dwelling (0), fixed on the walls and distributed homogeneously throughout the rooms of said dwelling. Referring to Figure 1, the system comprises one or more thermometers (2) disposed in the rooms of the dwelling (0). The thermometers are configured to read the temperature (Tint) inside the rooms of the house (0). The thermometer or thermometers (2) can be in the form of an independent housing disposed in one or more rooms of the dwelling (0) or in the form of a housing integrated in the heating devices (1). Each thermometer (2) is generally associated with a heating device (1) for measuring the ambient temperature of the room of the dwelling (0) in which said heating device is installed.

Referring to Figure 1, the system generally includes a thermostat (3). The thermostat (3) is generally in the form of one or more housings disposed inside the house (0) and incorporating various electronic circuits which will be described later.

The thermostat (3) is connected to the thermometers (2) so as to be informed of the measurements of the temperature inside the dwelling (0). The thermostat (3) is connected to the thermometers (2) by means of a wired connection (electrical wire, Ethernet cable, fiber optic, power line carrier, etc.) or wireless type radio waves (Wifi, Bluetooth, etc. .) or light waves (infrared, etc.). In practice, the thermometers (3) emit to the thermostat (2) data concerning the temperatures they fall under. The data is in the form of codes or pieces of analog, digital or other codes.

The thermostat (3) is also connected to the heaters (1) by means of a wired or wireless connection equivalent to those previously described.

With reference to FIG. 1, the system comprises means (4) for comparing the temperature measured (Tint) by the thermometer to a temperature of setpoint (Tcons) associated with each heating device (1). This means (4), generally disposed inside the thermostat (3), may be in the form of an electronic card that can integrate electronic components such as resistors, capacitors, transistors, comparators, or any other component suitable for the skilled person. In particular, the electronic card may include a microprocessor configured to perform the steps of a computer program stored in a memory. These steps make it possible to compare the temperature measured (Tint) by the thermometer (2) with a reference temperature (Tcons) associated with each heating device.

The set temperature (Tons) associated with a heating device (1) corresponds to the ambient temperature that must be approached in the room of the dwelling (0) in which said heating device is located. The set temperatures (Tons) may be the same for all the heating devices (1) or may be different for each of said heating devices (1) depending on the room of the dwelling (0) in which they are willing. The set temperatures (Tons) can be set on the thermostat (3) or on the heater (1) by means of a potentiometer (8) as shown in Figure 2, a multi-position switch, etc. . The setpoint temperatures (Tons) can also be stored in a memory generally disposed within the thermostat (3). In practice, and in order to ensure the comfort of the user, the target temperatures (Tons) can vary between an optimal comfort temperature (Tconf-opt) of about 23 ° C and a moderate comfort temperature (Tconf- mod) of about (19 ° C).

With reference to FIG. 1, the system comprises a control means (5) configured to control each heating device (1) so as to reduce the difference between the measured temperature (Tint) and the set temperature (Tcons) which is associated with him. In practice, this means (5), generally disposed inside the thermostat (3), transmits to the heating devices (1) data. This data can be configured to control the start-up or shutdown of the heaters (1). These data can also be configured to control the heating value released by the heaters (1) so as to quickly obtain a temperature measured (Tint) equal to the set temperature (Tcons).

In summary, to regulate the temperature inside a room of the dwelling (0): the temperature (Tint) is raised inside the room, - the temperature recorded (Tint) is compared to a temperature deposit

(Tons) associated with the heating device (1) arranged in the room, the heating device (1) is controlled so as to reduce the difference between the measured temperature (Tint) and the set temperature (Tons) associated therewith .

As shown in Figure 2, the system comprises means (6) for collecting on a remote network information relating to the thermal trend (Text) outside the dwelling (0). The means (6) can be in the form of an electronic card disposed inside the thermostat (3) and can integrate electronic components such as those described above and in particular a microprocessor. The remote network may be of the type network, internet network, intranet network including thermal measuring instruments or any other network suitable for the skilled person. The system then comprises means (7) for reducing the set temperature (Tcons) when the thermal trend decreases. The means (7) can be in the form of an electronic card disposed inside the thermostat (3) and can integrate electronic components such as those described above and in particular a microprocessor. In practice : if the information collected on the network indicates a thermal trend corresponding to an "ordinary" day, then the set temperature (Tons) is unchanged, if the information collected on the network indicates a thermal trend corresponding to a "cold" day, then the average (7) decreases the set temperature (Tons) by 1 ⁰ C,

- If the information collected on the network indicates a thermal trend corresponding to a day "very cold" then the means (7) decreases the set temperature (Tons) of 2 ° C.

In summary, to regulate the temperature inside the dwelling (0) so as to minimize energy consumption without significantly degrading the comfort of the user:

- Information on the thermal trend (Text) outside the dwelling (0) is collected on a remote network, the set temperature (Tcons) is decreased when the thermal trend decreases.

A first exemplary embodiment concerns information relating to the thermal trend (Text) outside the dwelling (0) collected on an intranet network comprising a thermometer (13) disposed outside the dwelling (0) . In practice, the intranet network can be summed up as an "average (6) - external thermometer" link of the wired, wireless or mixed type. The information collected by the means

(6) correspond to the temperature recorded by the thermometer (13) outside the dwelling. To reduce or not the set temperature (Tons), the means (7) is based on predefined temperature intervals corresponding to different thermal trends, for example:

- an outside temperature above 15 ° C corresponds to an ordinary day,

- an outside temperature between 15 ° C and 5 ° C corresponds to a cold day, a temperature below 5 ° C is a very cold day.

Thus, for this example of predefined intervals: if the information collected on the network corresponds to an outside temperature of 16 ° C then the set temperature (Tcons) is unchanged, - if the information collected on the network corresponds to a temperature outside measured by 11 ⁰ C then the means (7) decreases the set temperature (Tons) by 1 ° C, if the information collected on the network corresponds to an outside temperature read by 0 ⁰ C then the means (7) decreases the set temperature (Tcons) of 2 ° C.

A second embodiment relates to information relating to the thermal trend (Text) outside the dwelling (0) collected on an Internet network. In this case, the electronic card includes an internet interface of the type, modem, Ethernet card, usb card, wifi card, wimax card, etc. In practice, the data collected on the internet correspond to outdoor temperature measurements made by meteorological companies. The means (7) for decreasing the set temperature (Tons) functions in a manner similar to the preceding example.

A third embodiment relates to information relating to the thermal trend (Text) outside the home (0) collected on the electrical network. The information collected is tariff data transmitted over the electricity grid and corresponds to the electricity supplier's advanced billing systems. They are usually based on the thermal trend (Text) outside the home (0). For example, electricity providers such as EDF ^® offer subscription billing systems in which pricing varies according to weather conditions. In principle, for a subscriber to the service, the rate will be "disadvantageous" on days deemed "cold", "very disadvantageous" days considered "very cold", but "advantageous" the other "days". Supplier usually installs in the dwelling of the subscriber an alarm signaling, day by day, what is the method of pricing used. The supplier then broadcasts data relating to current pricing on its electricity network. This data is then decoded by the alarm installed in the home (0) of the subscriber. The warning device may, for example, be in the form of a warning light:

- which lights up in blue on days considered cold, that is to say when the pricing is disadvantageous,

- which turns red on days considered very cold, that is to say when the tariff is very disadvantageous, which remains off the rest of the time.

So, for this example of electricity supplier billing:

- if the information collected on the network corresponds to an "advantageous" tariff then the set temperature (Tcons) is unchanged, - if the information collected on the network corresponds to a tariff

"Disadvantageous" then the means (7) decreases the set temperature (Tons) of 1 ⁰ C,

- If the information collected on the network correspond to a "very disadvantageous" pricing then the means (7) decreases the set temperature (Tons) by 2 ° C.

Referring to Figure 2, the system may further include a clock (9) generally disposed within the thermostat (3). This clock (9) can be mechanical or electronic. The clock (9) can be updated manually by means of a user interface connected to the thermostat (3). This interface may include buttons, a touch screen or not, a digital display, etc. The clock

(9) can also be connected to a network for its automatic update. For this purpose, and referring to Figure 2, the system may include a means

(10) for collecting time data over a network. The temporal data can be located on a network of the internet type. In this case, the system may include an electronic card disposed inside the thermostat (3) and connected to the internet that can integrate electronic components such as those described above and in particular an internet interface.

The temporal data can also be located on a wireless network. In this case, the system may comprise a receiver configured to receive a radio signal stream and connected to a radio signal receiving antenna. This receiver can be of the television receiver type connected to a television antenna or the type of radio receiver combined with a radio antenna. The receiver is generally in the form of an electronic card disposed inside the thermostat (3) and incorporating electronic components such as those described above. The receiver is generally combined with a demodulator configured to demodulate all or part of the radio signal stream. The demodulator is generally in the form of an electronic card disposed inside the thermostat (3) and incorporating electronic components such as those previously described. The system then comprises means for extracting temporal data from the demodulated signals. This means is generally in the form of an electronic card disposed inside the thermostat (3) and incorporating electronic components such as those previously described. In summary, to collect available temporal data over a radio network: a radio signal stream is received via a receiver disposed inside the thermostat (3) and connected to a radio signal receiving antenna, all or part of the signal flow is demodulated, time data is extracted from the demodulated signals.

Time data can still be located on the power grid. The system can then include a means for updating automatically clocking (9) by synchronizing it with the transmission times of the tariff data conveyed on the electricity grid corresponding to the advanced billing systems of the electricity supplier, said tariff data being issued every day at the same time.

Referring to Fig. 2, to exploit the collected time data, the system generally comprises means (11) for adjusting the clock based on the collected time data. This means (11) can be in the form of an electronic card disposed inside the thermostat (3) and can integrate electronic components such as those described above, and in particular a microprocessor.

As shown in FIG. 2, the system may comprise means (12) for varying the target temperatures (Tcons) as a function of time ranges (Ph) of predefined setpoints. These time ranges (Ph) setpoints are programmed relative to the clock (9). This means (12) can be in the form of an electronic card disposed inside the thermostat (3) and can integrate electronic components such as those described above, and in particular a microprocessor. Time slots (Ph) are generally divided into two categories, the time slots (Php) and the hours of absence (Pha), but can also be divided into other categories suitable for the skilled person. The time slots of presence (Php) correspond, in principle, to the times when the user is supposed to be present in his house (0). The hours of absence (Pha) corresponding to the rest of the time, that is to say at the times when the user is supposed to be absent from his home (0). In certain cases, the hours of absence (Pha) may include the supposed moments of presence of the user for which said user can dispense with a comfort temperature, for example, the periods of sleep during which the temperature inside the house can be lower than the temperature in the evening. For example, we can take as hours of presence (Php), the following time slots: Monday to Friday, the morning from 7am to 9am and the evening from 18h to 23h, Saturday and Sunday, the day from 9am to midnight, the hours of absence (Pha) corresponding to the rest of the time.

In practice, and in order to achieve energy savings, the set temperature (Tons) is lower during the hours of absence (Pha) than during the time periods of presence (Php). In general, during the time periods of presence (Php), the set temperature can take a value equal to a comfort temperature (Tconf) between the optimum comfort temperature (Tconf-opt) and the moderate comfort temperature (Tconf) -mod). On the other hand, during the hours of absence (Pha), the set temperature generally takes a value equal to a saving temperature (Téco). In practice, the latter is around 18 ° C.

The time slots (Ph) may be common to all the heaters (1) or be specific to each of said heaters depending on the room in which they are arranged. The time slots (Ph) can be stored in a memory disposed inside the thermostat (3), and be set directly on said thermostat. Time slots can also be set on each heater (1) by selecting one of several operating modes. For each operating mode, the setpoint temperature (Tcons) varies according to predefined set time periods (Ph). In practice, each heating device (1) comprises one or more selectors for selecting one of the operating modes. These selectors may be in the form of one or more switches, pushbuttons, keys or any other form suitable to those skilled in the art. For example, for a heater comprising a "week" selector (14) corresponding to the first five days of the week (Monday to Friday) and a "weekend" selector (15) corresponding to Saturday and Sunday. Each selector (14, 15) has two modes of operation: "day" and "night". With regard to the "week" selector (14), the "day" operating mode corresponds to the "7:00 to 9:00" and "18:00 to 23:00" time slots (Php), and the "night" operating mode "Corresponds to the time zone of presence (Php)" from 22h to 9h ". With regard to the "weekend" selector (15), the "day" operating mode corresponds to the "9 pm to midnight" presence (Php) time slots, and the "night" operating mode corresponds to the time slot of presence (Php) "from 23h to 10h". Thus, for a heating device arranged in the kitchen, it is possible to set the "week" (14) and "weekend" (15) selectors to "day", for a heating device arranged in a room, it is possible to set the selectors "Week" (14) and "weekend" (15) on "night", etc.

The system may advantageously comprise one or more detectors (16) of presence of users disposed in the dwelling (0) or in each room of the dwelling (0). The presence detector (s) (16) may be in the form of sensors (photosensitive sensors, infrared sensor, ultrasonic sensor, infrasonic sensor, etc.), detectors arranged on the electrical network configured to locate in each of the rooms of the room. housing (0) the use of lighting, or any other means suitable for the skilled person. The detectors (16) can be arranged at the entry (s) of the dwelling (0) or in each room of the dwelling. The detectors (16) can communicate with the thermostat (3) via wired or wireless links. The system then comprises a means for adjusting the target temperatures (Tcons) according to the presence or absence of users in the dwelling (0). This means can be in the form of an electronic card disposed inside the thermostat (3) and can integrate electronic components such as those described above, and in particular a microprocessor. In practice, during a system operation of adjusting the set temperatures according to the presence or absence of user in the dwelling (0): - the presence of users in the dwelling is detected (0 ), the set temperature (Tons) for each heating device is set to a comfort temperature (Tconf) if the presence of the user is detected, the set temperature (Tons) is set for each heating, at a saving temperature (Teco) if no user presence is detected.

According to a variant of the above operation, it is possible to set the set temperature (Tcons) to a comfort temperature (Tconf) only for certain heating devices, for example those arranged in the kitchen and in the living room, but not those arranged in the bathroom and the laundry room.

Similarly, during a system operation of adjusting the set temperatures according to the presence or absence of user in each room of the house (0): it detects the presence of users, we rule the set temperature (Tons), of the heating device arranged in the room, at a comfort temperature (Tconf) if the presence of the user is detected, - the set temperature is set (Tcons), the heating device placed in the room at a saving temperature (Teco) if no user presence is detected.

The system can cleverly comprise means (17) for modifying the set time ranges (Ph) as a function of the actual presence time slots (Phpr) detected users. This means (17) can be in the form of an electronic card disposed inside the thermostat (3) and can integrate electronic components such as those described above, and in particular a microprocessor. The actual presence time ranges (Phpr) of the users are measured by the presence detectors (16). The set time periods (Ph) can be modified to start earlier than the actual time slots (Phpr) of the users, so as to anticipate the arrival of the user by controlling the heating of the heaters ( 1) slightly before the arrival of the user. This makes it possible to guarantee an ambient temperature inside the house close to the set temperature (Tcons) at the arrival of the user. In order to obtain time ranges (Ph) of instructions even more adapted to the habits of the user, averages of the periods of presence can be realized on the month, the year, etc.

By taking again the example of the previously described set time range (Ph) for which the time slot of presence (Php) is initially for Wednesday "from 07h to 9h and from 18h to 23h", and supposing that the user has used to spend Wednesday afternoon in his home (0), the thermostat then adapts to the behavior of the user by changing the time range (Ph) of the initial setpoint of Wednesday into a new time slot (Ph) setpoint for which the time slot is (Php) "from 07h to 9h and from 12h to 23h") corresponding to the actual presence time range (Phpr) measured by the presence detector (16).

The means previously described and implementing electronic cards may be in the form of separate electronic cards, in the form of a single electronic card combining all the means or in the form of several electronic cards, some of which may combine several means or any other form suitable to those skilled in the art.

All data collected or recorded, data on time slots, temperatures, gradients, climate, the presence of users, etc., can be stored in one or more memories arranged inside the thermostat (3).
